RE:RE:Drilling at Chidliak
RE:RE:Drilling at ChidliakMeans they cannot progress further with it or they cant recover more information from it. Sometimes it freezes, sometimes it becomes locked, sometimes casings become jammed or the drill wont turn. In the Arctic many times its because its frozen and it wont turn so you cant drill more or pull out.
Unforgiving place to work and unfortunately it is common even at shallower depths. I have been on site where a driller could not pass 40m because of permafrost issues.
